Same here, and the culprit might be a transparent forwarding page, nobodycares.ca/dw.html which lets you click through, but not back to the previous page.

Why do you want to go back to something you've already read?
I was pulling your stringI don't necessarily want to go back to something I already read. After reading a post, I want to go back to the forum page to read other posts.
back button works for me (IE 11)...
Can you right-click and choose 'Back'?
